What caused the Rokslide shift to smallest caliber and cartridges?
No worries, that wasn't directed at you. I was getting annoyed at someone else's nonconstructive one-sentence posts and their refusal to elaborate and just decided to throw out a little bit of a rant there. In response to some of TaperPin's comments, I'd bring up some of the pictures of wound... -

What caused the Rokslide shift to smallest caliber and cartridges?
The M1 Garand does not use a detachable magazine, at least not according to the conventional view. It has an internal fixed magazine fed by en bloc clips. At the time of the Garand's introduction the 1911, BAR, and Thompson SMG had all come into existence already, with the M1 Carbine following... -

What caused the Rokslide shift to smallest caliber and cartridges?
This is exactly correct. Obviously you can get a bullet in a larger caliber that will do far more damage than the best .223, .243, 6.5 Creedmoor, etc. can do, this is just basic physics. At the level demonstrated with this deer hit by .338 Lapua Magnum, clearly you do have more leeway for shot... -

Has anyone chronographed recent 2024 lots of Black Hills 77 gr TMK?
Re: OP Question I've clocked previous lots of 77 gr TMK from around 2020 at about 2700 FPS from a 16" barrel, consistent across rounds from 2 lots, in 2 different rifles, through 2 different chronographs. This has roughly matched ElPollo's data from 2024 as well as Molon's from 2023. Recently... -

.223 for bear, mountain goat, deer, elk, and moose.
There seems to be a sufficiently large pile of elk posted in this thread that I think we're beyond the level of isolated examples in respect to that particular breed of ungulate. IMO the value of the bear and moose reports is not so much in what they say about the suitability of 77 gr TMK for... -

.223 for bear, mountain goat, deer, elk, and moose.
This is a physiological oversimplification - obviously there are also factors to consider such as tissue density and the actual shape and form of various body parts - but it may be worth noting that it doesn't take a large increase in bone & muscle thickness/ballistic resistance to translate... -

.223 for bear, mountain goat, deer, elk, and moose.
This may be moving a bit outside the scope (no pun intended) of the original intent of this thread, but as someone who finds terminal ballistics an interesting subject, I've had this question on my mind: How wide would you guess the wound channels in lungs produced by .223 TSXs at higher impact... -

.223 for bear, mountain goat, deer, elk, and moose.
Do they look to be cannelured? I'd love to have an additional source of factory 77 gr TMK to complement my Black Hills stuff but I'd like to see something with cannelures and ideally the same POI; to that end, I wouldn't mind seeing some chronograph and zeroing information, if anyone gets the... -

.223 for bear, mountain goat, deer, elk, and moose.
Ah, I see that now. At first I had thought the exit wound was the small perforation? spot of coagulated blood? a couple ribs below the actual exit as it looked roughly the size of an expanded 77 gr TMK bullet. Impressed to see that the actual exit is significantly larger. This seems to evidence... -

Is that small hole at top left an exit? Looks like the bullet impacted at quite a steep angle. -

Call it a bonus, those plastic tips look like they're halfway to initiating bullet expansion already. -

Is the link for that still active? I've never seen cannelured TMKs sold standalone. -

.223 for bear, mountain goat, deer, elk, and moose.
M855 doesn't consistently and substantially outpenetrate many handgun rounds, at least not in muscle tissue. The "short NL" (neck length) example shown here is probably somewhat closer to the average wound profile at M4 muzzle velocities, and it's about as deep as many handgun hollowpoints go... -

.223 for bear, mountain goat, deer, elk, and moose.
Less consistent, longer neck, much higher velocity needed to deform, tends to be less explosive at all velocities though the difference becomes more pronounced as it approaches its frag threshold. Generally depends on yaw to initiate upset rather than the more reliable mechanism of hydraulic... -

.223 for bear, mountain goat, deer, elk, and moose.
Do awfully hate to ask, but it looks like I missed out on some of those sales and I'm planning a hog hunt in the next month. If anyone's willing to quote me a price on some Black Hills or 8208...and I live in the Cstat area, if there's anyone local. Now, I know this is just some more... -

.223 for bear, mountain goat, deer, elk, and moose.
Unfortunately I haven't personally shot any deer with them, but just from what I know of bullets in general: 73 gr ELD-M, as a fragmenting polymer-tipped hollowpoint, will also create wide wound channels, but as per both ballistic gel testing and anecdotal reports tends to penetrate... -

in my experieints...it is very comon for deer and moose to play dead. even with 4 inch holes in there body. once i hit a deer with 20mm DU penetrator APIFSDS. after a 120 yard run i thought the lihtes had left him...dressed and preped him to cook. later at dinner i got the worst hernea of my... -

.223 for bear, mountain goat, deer, elk, and moose.
It appears we have some new information on the velocity threshold of the 77 gr TMK. This video seems to show that 77 gr TMK is still expanding well at velocities of 1650 FPS, which would seem like justification to revise my previous estimates of 1650-1700 FPS down to 1550-1600 FPS. Firing the... -

Out of spec feed ramps or parts can cause issues with tipped bullets; if the bullet is impacting at an excessively steep angle and/or there's not enough space in the barrel extension cutouts you can see problems. If your rounds are feeding at the appropriate height into correctly shaped ramps...
